| 摘 要： | 本文以六倍体小黑麦H87—287,H87—291为参试种,观察六倍体小黑麦和开花习性,认为六倍体小黑麦的开花与小麦相似;一般从开花到终花持续6.7天,开花后2—4天为盛期;从一天来讲,白天开花的数量占多数;雌蕊柱头的生活力可以持续11天,但在开花后第3—5天的生活力最强;六倍体小黑麦的异交率很高,约在40％。这些对小黑麦的育种及良繁有一定参考价值。

| Abstract: | In this paper we use two varieties of hexaploid trical. cv H87-287, H87-291 for experiment. We observed that the flowing habit (hexaploid tritical is similar to that of) wheat (Trilicum aestivm) i. e its fading away, and there is a blossom peak of 2-4 day after flowering. As for a whole day the majoity of the flowers are in blossom. The vitality of its pistil stigma can sustain ,and which is the highest from the 3rd day to the 5th after flowering, the cross bertilization percentage of hexaploid tritical is so high that it reaches about 40%. It is significant that the above observation and test be taken for reference in the breeding and propagation of hexaploid tritical. |
